How Much Does It Cost to Upgrade an Electrical Panel?

Quick Answer 

There’s no flat price we can give you here, and that’s on purpose. Every panel upgrade depends on your home’s current wiring, your panel’s age and condition, the amperage you need, and what your local code requires. The only way to get an honest, accurate number is to have a licensed Golden Rule electrician take a look at your system in person. 

Why Every Panel Install Is Different 

No two panel upgrades look exactly the same, even on homes that seem similar from the outside. The right approach depends on things like how your home is currently wired, whether that wiring meets current code, how far the panel is from your meter, what size panel your home actually needs, and whether local permitting adds extra steps. A home with hidden wiring issues or an outdated grounding setup can turn what looked like a simple swap into a bigger job. 

That’s why a phone estimate, or a guess based on a photo, isn’t reliable. A licensed electrician needs to physically inspect your panel, your wiring, and your home’s electrical load before they can give you a number you can trust. 

Red flag: if an electrician gives you a firm price before ever stepping inside your home or opening your panel, be cautious. A trustworthy electrician will want to see your system in person first. Golden Rule electricians always start with an in-home visit, so the quote you get reflects what your home actually needs — not a generic guess. 

Symptoms: Signs You May Need a Panel Upgrade 

• Breakers trip often, even when you’re not running many appliances at once 
• Lights flicker or dim when the AC, dryer, or another large appliance turns on 
• The panel feels warm to the touch, hums, or gives off a burning smell 
• You still have a fuse box, or a panel that’s more than 25 to 30 years old 
• You’re out of open slots and want to add an EV charger, hot tub, or home addition 
• The panel’s metal box looks rusted, discolored, or has visible scorch marks 
• Breakers rarely or never trip — even during storms, overloads, or heavy appliance use 

*The last point sounds backwards, but it’s an important one. A breaker that never trips can be more concerning than one that trips too often. In some older panels — Federal Pacific “Stab-Lok” panels especially — the breakers fail to trip during an overload, so the circuit keeps drawing power instead of shutting off. That’s part of what makes those panels a fire risk. Every home’s breakers should trip once in a while; if yours never do, it’s worth having an electrician check why. 

Causes 

• Your home uses more electricity than it did when the panel was installed — bigger TVs, more electronics, central air, and other modern appliances all add demand. 
• Components inside an older panel wear out over time. Breakers can weaken and stop tripping the way they should, and connections can corrode. 
• Some older panel brands and models have known safety issues that make replacement the safer choice — see the list below. A licensed electrician can tell you if yours is one of them. 
• Home additions, finished basements, workshops, or new large appliances add electrical load the original panel wasn’t built to handle. 

Panel Brands That Are Not Recommended 

A handful of older panel brands have a well-documented history of safety problems. If your home has one of these, it’s worth having an electrician take a look, even if you haven’t noticed any warning signs yet. 

Not Recommended 

Federal Pacific Electric (FPE) / Federal Pacific “Stab-Lok”: the most notorious name in this space. Independent testing found a high failure rate in Stab-Lok breakers not tripping under overload conditions, which can lead to overheating and fire. These panels were installed widely in homes built between the 1950s and 1980s, and many insurers will refuse coverage or require replacement before they’ll insure a home. 

Zinsco / Sylvania-Zinsco: a similar issue — breakers can fail to trip, and the metal bus bars inside the panel are prone to overheating, melting, and arcing (sparking). Most common in homes built in the 1960s and 70s, mainly in the western United States. 

Challenger: breakers in these panels have a known tendency to fail to trip properly. To complicate things further, Challenger’s assets and issues were later absorbed by Eaton/Cutler-Hammer through corporate acquisitions, which has muddied the availability of matching replacement parts. 

Sometimes Flagged, More Situational 

Pushmatic / Bulldog Pushmatic: not necessarily unsafe by design, but the company went out of business decades ago. Replacement breakers are hard to find and often rely on old stock or aftermarket reproductions, and many of these panels are now simply worn out from age. 

Sylvania (non-Zinsco branded): also discontinued, with similar parts-availability concerns as Pushmatic. 

Not sure what brand your panel is, or whether it’s on this list? A Golden Rule electrician can identify it during an inspection and tell you exactly where things stand. 

DIY vs. Pro 

Homeowners can safely handle a few basic things: resetting a tripped breaker, labeling breakers so you know what controls what, and doing a visual check for rust, scorch marks, or a loose panel door. That’s where DIY should stop. 

Opening the panel cover, replacing breakers, or swapping the panel itself is not a DIY project. The panel connects directly to the power coming into your home, and parts of it stay energized even when individual breakers are off. This work should always go to a licensed electrician, and most areas require a permit and inspection for a panel upgrade. 

Technician tip: our electricians always check whether the breakers inside a panel are all the same brand as the panel itself. Mismatched breakers are a common sign that someone did unpermitted work in the past, and it’s one of the first things a licensed electrician will want to correct during an upgrade. 

Seasonal Considerations 

Electrical panels get pushed hardest during extreme weather. In peak summer heat, air conditioners run longer and draw more power, which can expose a panel that’s already near its limit. In cold winter months, furnaces, space heaters, and heat tape add extra load at the same time. If your panel is already showing warning signs, extreme temperatures are often when problems show up first — a good reason to have it checked before the next heat wave or cold snap rather than during one. 

FAQ 

Q: How long does an electrical panel upgrade take? 

A: Most upgrades take a few hours to a full day. Your power will need to be shut off for part of that time. 

Q: Do I need a permit to upgrade my panel? 

A: In most areas, yes. A licensed electrician will typically handle the permit and schedule the required inspection. 

Q: What size panel do I need? 

A: Many newer homes use 150- or 200-amp panels. Older homes often have 60- to 100-amp panels, which may not support modern electrical needs. An electrician can calculate the right size for your home. 

Q: Can I upgrade my own panel to save money? 

A: No. This work involves the main power feed into your home and carries a serious risk of shock or fire if it’s not done correctly. It should always be done by a licensed electrician. 

Q: Will upgrading my panel affect my homeowners insurance? 

A: It can. Some insurers charge more, or decline coverage, for homes with fuse boxes or very old panels — including the not-recommended brands above. Upgrading can sometimes lower your premium — check with your insurance provider. 

Q: How much will a panel upgrade cost? 

A: There’s no set price. It depends on your panel’s age, your home’s wiring, the amperage you need, and local permit fees. The best way to get an honest number is to schedule an in-home electrical assessment with a licensed Golden Rule electrician.
